alt-whom it may concern: :f-Bei itylgnown that I, Russnmt. Minion, ucitize'ni of the United States, residing at kllent'own, in the county of Lehigh and State of lgennsylvani'a hate invented-a cer- Jain newcand useful improvement "in Car- BrakeQperating Mechanism, of which the following is'a specification.

My invention relates to a new and'useful improvement in brake operatin mec anisni, and has for its object to provi e'an'exccedingly simple and effective device of this character which will be inexpensive yet strong and durable, the style here shown hemg especially designed for a car without a bumper beam.

Another object of the invention is to provide a device of the character described leased mm the top or side of a car.

Af'further obi'ect of the invention is to rovide a simlp e and eiiective mechanism or retaining t e brake handle or wheel in a fixed'position after it has been moved, withsimilar device.

A still further object is to provide means for quickly taking up the slack in the connectin cable or chain.

Wit these ends in view, this invention combination of elements hereinafter set forth and then specifically designated by the In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by 'letter to the accompanying drawing forming a part of this specification, in which a T Figure 1 is an end view of a portion of a car showinv myimproved brake mechanism applied thereto, the casing being in section, and Fig. 2, a side elevation thereof, the casbodied, A represents a car. the style here represented being one without a bumper beam.

ed the casing B, having the rear end open and provided with -an extension C which rests against the end Of tll car to prevent its being forced inward should it come in con tact with some outside object. \Vith the extension C-is formed an integral bracket D,

having a bearin ll fo'r the shaft F, which extends beyond the fside of the car, and-has a hand Wheel' G mounted-thereon; On the opposite end ofthis shaftisnio'unted a bevel gearH which meshes-with the bevel ear I mounted upon the shaft J Sena shaft 'eing held in a vertical straps K and-'exten ing above the top'of the car, at which point it is provided with a osition by themetallic v hand wheel L. The lower end of the shaft J extends into and is journaled' in the casing B the end thereof resting upon the bearing M. On this shaft is also mounted the worm N, which meshes with the ear 0 mounted upon the horizontal shaft 5, said shaft beiiw journaled in the sides of the casin an the gear 0 is mounted a cam block Q to the highest ortion of which is secured one end of the rake rig ing R. The cam block Q, takes up the slac in the brake rigging as soon as the shaft is partially revolved, so that it requires no wasted energy in bringing the parts to their operative .positions.

The bottom of the casing B is turned up, as indicated by S forming a chamber to hold a lubricant solthat the bearings are always properly lubri ated.

From the foregoing description it is apparent that when either of the wheels G or L is turned the brake rigging R will be operated, the flexible portion thereof en aging the cam block Q until it is fille at which time it runs upon the shaft P. By the use of the worm N and the gear 0 the brake mechanism can be easily operated from either the top or side of the car and it is unnecessary to have the ordinary ratchet wheel andpawl because the gear 0 will not operate the worm N.

Of course I do not wish. to be limited to,

the exact details of construction here shown, as these ma be varied within the limits of the appen ed claims without departing from the spirit of my invention. n I Havin thus fully described my invention, what I c aim as new and useful, is 1. In a car brake mechanism, the comb nation with a car and the brake rigging thereof, of a casing mounted on the under side of the car on oneend thereof, the bottom of said casing being turned it a at one end to form a lubricant chamber, a 1or1a0ntal shaft journaled in the side of Sfl1"l casing, a gear mounted on said shaft, a cam block mounted on one side of the gear to which is attached the flexible end of the brake rigging, a vertical shaft, the lowenencl being ournaled in'the easing, the upper end extending above the car and having a 'hand said shaft and meshing with the gear, a be'vel glear mounted upon said shaft, another s aft extendin' to the side of the car having a hand whee mounted thereon, and another 'bevel ear mounted on said shaft andmeshing with the first named bevel gear.

2. In combination with a car and the brake rigging thereof a casing having the rear end open mounted beneath a car at one end thereof, an extension formed therewith adapted to rest against the end of the'car, a;

bracket formed integral with said extension provided with a bearing, a shaft iournaled in said bearing and extending to the side of the car, a hand wheel mounted thereon, a bevel gear mounted on the inner end of said shaft, a vertieal shaft passi through the casing and ournal therein e upper end extending above e to of the car, a

' han wheel mounted on t e upper end wheel mounted thereon, a worm mounted on mash ie'straps for holding said shaft in position, a bevel ar mounted on said shaft and'meshing wit the first named bevel gear, a worm also mountedon said shaft, a horizontal shaft journaled in the sides of the casing, a ar mounted thereon adapted to mesh wit the worm, d' a oam block mounted on the side of t e ear, towhich is attached the flexible end 0 the 'brakei'rig- In testimony whereof, I have hereunto affixed mv signature in the presence of two subscribmg witnesses RUSSELL H. MINICH.
